NOTICE
The handling of Cationic Emulsions (CRS-2, CMS-2, CSS-1 and CSS) may
create an environment within the Asphalt Distributor that can be corrosive to
carbon steel and cast iron.
•Cationic Emulsions are widely used within the industry.
•Cationic Emulsion is manufactured with asphalt, water, emulsifiers and
hydrochloric acid. The chemistry of individual emulsions varies in asphalt
content and Ph levels.
•Tanks and spray mechanisms used with Cationic emulsions may experience
corrosion
•It is believed the chemistry of the emulsion - specifically the residual fumes
promote the corrosion
• Etnyre Distributors are compatible with Cationic Emulsions provided that
certain precautions are taken.
•Prior to placing a distributor in to service with Cationic Emulsion, it should be
loaded with an AC or MC type material to develop a protective coating.
• Periodic inspection of the tank and spray system should be preformed in the
normal course of operation.
• It is recommended that distributors used in Cationic service be flushed
periodically and at the end of the season with an AC, MC or cutback to
remove the corrosive materials and to provide a protective coating.
•Increasing the quantity of flushing material during daily suck back and
cleanout operations will also help to minimize corrosion damage.
•Dilution is the solution.
• Additional information can be acquired from your Emulsion supplier as well as
the Asphalt Institute or the Asphalt Emulsion Manufactures Association.
WARNING
Take extra care and follow recommended
procedures when alternating asphalt materials
especially when loading hot product, over 212
degrees Fahrenheit (100 degrees Celsius), on
to a tank and system previously in Emulsion
service.

General Safety Instructions
DANGER
To avoid an extreme fire hazard or explosion,
NEVER use gasoline as fuel in diesel or fuel
oil burners.
WARNING
A fully charged dry chemical type fire
extinguisher must be within easy reach
whenever the burners are operating or there
is an open flame near the Distributor. The
minimum capacity of the fire extinguisher
should be 10 pounds.
Please Note This Warning
and Remember:
• Always start and operate the engine in a
well ventilated area.
• If in an enclosed area, vent the exhaust to
the outside.
• Do not modify or tamper with the exhaust
system.

WARNING
A fully charged dry chemical type fire
extinguisher must be within easy reach
whenever the burners are operating or there
is an open flame near the Distributor. The
minimum capacity of the fire extinguisher
should be 10 pounds.
Fluoroelastomer Handling
Some O-rings and seals used in this vehicle
are made from fluoroelastomers, When used
under design conditions, fluoroelastomers do
not require special handling. However, when
fluoroelastomers are heated to temperatures
beyond their design temperature (around
600º Fahrenheit), decomposition may occur
with the formation of hydrofluoric acid.
Hydrofluoric acid can be extremely corrosive
to human tissue if not handled properly.
A degraded seal may appear as a charred or
black sticky mass, Do not touch either the
seal or the surrounding equipment without
wearing neoprene or PVC gloves if
degradation is suspected. Wash parts and
equipment with 10% lime water (calcium
hydroxide solution) to neutralize any
hydrofluoric acid.
If contact with the skin occurs, wash the
affected areas immediately with water. Then
rub a 2.5 calcium gluconate gel into the skin
until there is no further irritation, while
seeking prompt medical attention.
Note to Physicians: For advice or treatment
of HF burns, call the DuPont Medical
Emergency number, 1-800-441-3637.
To prevent an explosion or fire hazard:
• Position the unit broadside to the wind to
prevent volatile fumes from drifting toward
the burners.
• Do not operate the burners if the tank is
damaged or leaking.
• Ensure that the burners are extinguished
before removing any material from the tank
in any manner. Liquid petroleum (LP)
burners can support a flame for several
minutes after the fuel supply is turned off.
To prevent an explosion or fire hazard:
• Do not operate the burners when the vehicle
is unattended, when the vehicle is in
motion, or with the vehicle in a confined
area.
• When the burners go out, shut off the fuel
supply to both burners and allow the flues to
ventilate for at least 3 minutes before re-
lighting the burners.
• Do not heat the material beyond the
manufacturer’s recommended temperature.
• Keep burning cigarettes or other sources of
combustion away from manholes and
overflow vents.
• Keep area free of all sources of combustion
when spraying.
• Check the tank vent to insure that it is free
from obstruction before lighting the burners.
• Eliminate sparks from engine exhaust.
• Do not operate the burners with the
manhole open or open the manhole while
the burners are in operation.
• Flues must be covered by a minimum 6
inches of material (bitumen) when burners
are in operation.
To prevent possible hand or facial burns:
• Always light the inside burner first. Do not
reach across a lit burner to light or re-light the
inside burner. Shut off the outside burner
before lighting the inside burner.
To prevent possible burns:
• Always use a torch to light the burners.
Never attempt to light the burners using a
match or pocket lighter.
• Always wear insulated gloves when
handling spray bar sections or hoses.
• Always wear eye protection, face shield,
long sleeve shirt, insulated gloves, boots,
and long pants outside the boots when
working around the Distributor.
• Use extreme caution when using a torch to
heat the pump. Asphalt accumulated around
the pump may ignite when heating the
pump with a torch.
WARNINGS

9
WARNINGS
To prevent possible burns from leaking
material:
• Be sure all pipe, cap and hose connections
are secure before opening valves, or
beginning any operation.
To prevent possible burns from hot
asphalt spray:
• Do not stand, or allow anyone to stand,
where accidental opening of a valve may
cause contact with hot asphalt.
To prevent possible burns from foaming
or violent eruption:
• Do not load tank with material temperature
over 200ºF if water or condensation is
present in tank, or if emulsion was used in
the previous load.
• Do not heat material over 200 ºF if moisture
or emulsified material is present in tank.
To prevent burns from hot asphalt when
hand spraying:
• Hold the handspray gun in proper position
and watch for other people.
To prevent possible burns to operators or
bystanders, or possible equipment
damage:
• Do not start any operation if any control
settings are unknown.
To prevent severe injury from becoming
entangled in machinery:
• Stand clear of rotating drives.
To prevent possible injury:
• Always open the manhole cover slowly.
Pressure build up in the tank may cause
the cover to burst open.
To prevent possible fire hazards, burns or
falls:
• Keep the unit clean for safe operation.
To prevent possible burns from material
overflow:
• Allow sufficient space in the tank for
expansion of the material when heating
• Before removing the fill line cap, make
certain that the asphalt pump is turning and
the tank valve is closed.
WARNING
To prevent possible personal injury:
• Do not load the vehicle beyond the GAWR
or GVWR. The maximum load volume must
be calculated based on material density.
Allowing the burners to operate for a long period
oftime without circulatingcan damage the product
and create explosive fumes. If product cannot be
circulated after fifteen minutes of heating without
circulation,theburners should be extinguishedfor
20 - 30 minutes before re-lighting the burners.
Use the measuring stick as shown in Figure 9 in
the
UsingtheMeasuringStick sectionto determine
the amount of product in the tank before lighting
burners. The minimum amounts shown on the
warning placard only apply if the tank is level.
Remember that the measuring stick is accurate
only when the tank is level. Ifthe tankis notlevel,
repositionthe Distributorto placethe tankin alevel
positionbeforetaking finalmeasurement.Youmust
have at least the amounts shown, with the tank
level, in order to safely light the lower burner and
upper burner respectively. Failure to have the
appropriate amount, accurately measured can
result in an explosion causing death or serious
injury.

10
Foaming
WARNING
To prevent possible burns from foaming
or violent eruption:
• Do not load tank with material temperature
over 200 ºF if water or condensation is
present in tank, or if emulsion was used in
the previous load.
• Do not heat material over 200 ºF if moisture
or emulsified material is present in tank.
If the Distributor is to be filled with hot bitumen,
proceed very cautiously. If there is any moisture in
the tank, or if an emulsion product was the last
load, foaming or eruption may occur.
Dow-Corning DC-200 may be used to prevent
foaming in Distributors, Transports, and
Maintenance Units.
Mix the contents of one can (16 oz.) with one (1)
gallon of diesel fuel or kerosene. Add one (1) oz.
of this diluted mixture to each 1000 gallons of
asphalt. The correct amount may be poured
through the manhole. This will assist in reducing
foaming, particularly if moisture is present or if an
emulsified asphalt was used in a previous load.
Iffoaming does notoccur at thestart of theloading
operation, but you suspect that there may be
moisturein the spraybaror circulating system,the
loadingoperation shouldbestoppedwhenthe tank
is no more than 25% full. The product should then
be circulated through the spray bar at a rate of 80
to 100 GPM before continuing the loading
operation.
Iffoaming does occur, continue circulatinguntil the
foaming stops, and then suck back the product in
the spray bar back into the tank before filling the
tank the rest of the way.
Asphalt Institute

From the fully retracted position, spray valves as-
sociatedwith switch 4are the firstto beturned ON,
with switch 4 ON, as the spray bar is extended.
One Foot switches that are in the retracted portion
of a variable width spray bar do not add to the dis-
played spray width even if they are turned ON.
2. MASTER SPRAY Switch
Turningthis switchto ONwhen theFunction knob
(rear panel) is turned to BAR CIRCULATE or BAR
SUCK BACK, opens all activated spray valves. The
spray valves are allowed to open in BAR SUCK
BACK for troubleshooting. Turning the SPRAY
switch ON the LOAD/TRANSFER or TANK CIRCU-
LATE positions of the Function knob allows the ac-
cumulated values to increment for measuring.
3. TANK VALVE Switch
Selects between the standard REAR tank valve
andthe optional FRONTtank valve. FRONTshould
always be selected prior to spraying to eliminate air
in the load line. FRONT can then be selected at
anytime while spraying.
4. LEFT MARKER VALVE Switch
(Optional)
Activates the left side marker valve.
5. RIGHT MARKER VALVE Switch

6. SHIFT Switch
Moves the entire spray bar left or right. Holding
the switch in either direction moves the spray bar
continuously until the switch is released, or until
full right or left is obtained.
7. LIFT Switch
The bar latching position is when the spray bar
is completely centered and raised. Unlatch the
spray bar before lowering it. The spray bar may
need to be raised to allow the bar latching mecha-
nism to move. The spray bar cannot be lowered
beyond the height adjuster setting, which is set for
a spray height of 12 inches at the factory. The
height adjusters may be adjusted higher or lower
for individual preference. Also see the
Adjusting
Spray Bar Height
section.
8. BAR Latch Switch (Optional)
The bar latching mechanism will remain in the
desired position even though the switch does not.
The spray bar should be latched prior to transport
and unlatched prior to lowering for spraying.
9. WING FOLD Switches
Spray bars have fixed center sections and fold-
ing wings on both sides. Spray bars that have the
corresponding One Foot switches turned ON will
increase the spray width when the wing is lowered
anddecrease the spraywidth when raisedbeyond
thewing tiltswitchsetting. Itis alwaysa good prac-
tice to turn OFF the corresponding One Foot
switches before raising the wing while spraying.
10. Display
All information critical for Distributor operation
is displayed on this two-line LCD. When the sys-
tem is turned ON, the installed software version is
displayed for a few seconds, after which the first
of the operating screens is displayed. Additional
screens are used for setting up the computer. In-
formation messages flash over the entire display
to communicate critical information.
Refer to the
Setting up the Computer and Op-
eration Screens sections in this manual for more
information.
11. WARNING Light
Indicates that there is critical information to be

16. Power Switch
Both POWER switches, front and rear, must be
ON for the system to be ON. The entire system
canbe shut downby turning eitherPOWER switch
to OFF. Before turning either POWER switch to
ON be sure you know what will automatically acti-
vate.
17. SUCK BACK OVERRIDE Switch
When ON, this switch overrides the current set-
ting of the Function knob in the rear panel to the
SUCK BACK selection. The SUCK BACK OVER-
RIDE must be OFF for the Function knob and the
PUMP CONTROL switch to work correctly.
18. LEFT BAR Switch
Extends or retracts the left variable width spray
bar. Holding the switch in either direction moves
the spray bar continuously until the switch is re-
leased or until the spray bar is fully extended or
retracted. A single press of the switch in either di-
rection moves the spray bar 4 inches until it is fully
extend or retracted. If the spray bar, due to shift-
ing, does not fully extend or retract, holding the
switchin the desireddirection for 5seconds forces
the spray bar into position.

Rear Control Panel Descriptions
1. PUMP SPEED Control Knob
When MANUAL PUMP CONTROL is selected,
turning this knob to the right (clockwise) increases
theasphaltpump speed.It ispossibleto over-speed
the asphalt pump in MANUAL control since the as-
phalt pump speed is also dependent on the engine
speed. Always turn the knob back to the left
(counter-clockwise) before selecting AUTO PUMP
CONTROL or turning ON either POWER switches
(front or rear).
2. PUMP CONTROL Switch
Withtheswitchturned toAUTO,theasphaltpump
speed is controlled at the desired rate through the
computer which limits the maximum pump speed
to450 GPM. When theFunction knob is setto BAR
CIRCULATE, the pump speed is limited to a maxi-
mum of 120 GPM. With the switch turned to
MANUAL,theasphalt pumpspeedis controlledwith
the PUMP SPEED control knob.
In AUTO control, A flashes until the START but-
ton is pressed. In MANUAL control, M flashes until
the START button is pressed. Use Etnyre
computator (p/n 3390408) when spraying in
MANUAL control.
NOTE: Some early units were not wired so that
theSTARTbuttonmustbepressed beforethepump
can turn in MANUAL pump control.

pump rate, and also for calibration operations in
the setup screens. When the Function knob is
turned to BAR CIRCULATE, the displayed spray
width must be greater than zero for the pump to
start turning when the START button is pressed.
4. ENGINE HIGH IDLE Switch
Whenthis option isavailable and installed,turn-
ingON thisswitchmakes theengine runata higher
RPM. Turning OFF the switch resumes the engine
speed to idle. The high idle setting varies but can
be programmed to your preference through your
truck dealer. This switch is not disabled through
the POWER switch.
5. Wing Fold Switches
Spray bars have fixed center sections and folding
wings on both right and left sides. Spray bars that
have the corresponding One Foot switches turned
ON will increase the spray width when the wing is
lowered and decrease the spray width when raised
beyondthewingtiltswitchsetting.Itisalwaysagood
practice to turn OFF the corresponding One Foot
switches before raising the wing while spraying.
6. LOWER BURNER Switch
When an optional fuel oil burner is installed, this
switch directly controls the lower burner unless an
optional thermostatic control or brake interlock
switch is also installed. Then it is possible for the
switch to be ON when the burner is off. Before
operating the burner, refer to the
Burner Opera-
tion
section in this manual.

7. UPPER BURNER Switch
When an optional fuel oil burner is installed, this
switch directly controls the upper burner unless an
optional thermostatic control or brake interlock
switch is also installed. Then it is possible for the
switch to be ON when the burner is off. Before op-
erating the burner, refer to the
Burner Operation
section in this manual.
8. FUNCTION knob
When the desired operation is selected through
this knob, all automatic valves (tank valve, 4-way
valve, bar suck back valves, and balance valves)
are set for the desired operation, and the asphalt
pump stops and when the PUMP CONTROL is in
AUTO the stored asphalt pump rate target preset
for the desired operation is recalled. Changing the
selection after the pump is turning will stop the as-
phalt pump in AUTO or MANUAL control. When
BAR CIRCULATE is selected, the asphalt pump
rate target is calculated based on the displayed
spray width, application rate, and the setting of the
%CIRC factor. For all positions of this switch, ex-
ceptBAR CIRCULATE, the asphalt pumprate pre-
set can be set to operator preference by first se-
lecting AUTO PUMP CONTROL. Then before
pressing the STARTbutton, change the pump rate
targettothe desiredrateandthen press theSTART
button to save the desired rate and start the pump
turning.
The factory pump rate target presets are (With
Metric equivalents also):
• LOAD/TRANSFER 100 GPM
• TANK CIRCULATE 150 GPM
• BAR SUCK BACK 200 GPM
• BAR FLUSH 100 GPM
• UNLOAD 100 GPM
• HAND SPRAY 50 GPM
NOTE: Some early units were not wired for the
asphalt pump to automatically stop turning when
the FUNCTION knob selection is changed in
MANUAL pump control.
11. SHIFT Switch
Moves the entire spray bar left or right. Holding
the switch in either direction moves the spray bar
continuously until the switch is released, or until
full right or left is obtained.
12. LIFT Switch
The bar latching position is when the spray bar
is completely centered and raised. Unlatch the
spray bar before lowering it. The spray bar may
need to be raised to allow the bar latching mecha-
nism to move. The spray bar cannot be lowered
beyond the height adjuster setting, which is set for
asprayheightof 12inchesatthe factory.Theheight
adjusters may be adjusted higher or lower for indi-
vidualpreference.Also seethe

section.
13. BAR Latch Switch (Optional)
The bar latching mechanism will remain in the
desired position even though the switch does not.
The spray bar should be latched prior to transport
and unlatched prior to lowering for spraying.
14. WASH PUMP Switch and Light
When the optional solvent pump and switch is in-
stalled turning the switch ON will allow use of the
solvent wash wand or application of solvent to the
top of the asphalt pump without the pump turning. The
light is a reminder that the switch and pump are ON.
15. POWER Switch
Both POWER switches, front and rear, must be
ON for the system to be ON. The entire system can
be shut down by turning either POWER switch to
OFF. Before turning either POWER switch to ON be
sure you know what will automatically activate.
16. FRONT LOAD Switch (Optional)
When the optional front load switch is installed,
selecting Open when in the Load or Transfer posi-
tions of the Function knob will open the front load
valve. The Closed position allows the use of the
standard load line.
17. LEFT BAR Switch
Extends or retracts the left variable width spray
bar. Holding the switch in either direction moves
the spray bar continuously until the switch is re-
leased or until the spray bar is fully extended or
retracted. A single press of the switch in either di-
rection moves the spray bar 4 inches until it is fully
extend or retracted. If the spray bar, due to shift-
ing, does not fully extend or retract, holding the
switchin the desireddirection for 5seconds forces
the spray bar into position.

To prevent possible personal injury, do not
load the vehicle beyond the GAWR or
GVWR. The maximum load volume must be
calculated based on material density.
Setting Up the Computer
Before the Distributor is used, the control com-
puter has to to be set for each particular Distributor.
The setup screens are used to set parameters and
perform calibrations for the Distributor that the con-
trol computer is installed in. Setup is performed for
the customer at the factory and should not need to
be changed except for when major service or repair
is performed on the Distributor.
To enter the set up screens hold Memory 6 and
10buttons downwhile turningthe POWERswitchto
ON.Thenrelease the buttons.To exitthe setup, turn
the power OFF.Any changes that are made while in
the setup screens are automatically saved.
The SELECT switch is used to navigate through
the Setup screens, while the VALUE switch is used
to change the value that is selected. The START
switchisusedtoinitiatecalibrationproceduresinthe
Setup screens. Abbreviated instructions for the cali-
bration procedures are displayed for quick recall.
First Screen
This screen allows you to set the display units
and bar control. VALUE increase from English to
get Metric. VALUE increase from FOOT to get
GANG or decrease from FOOT to get VW (vari-
able width). Additional setup screens, for the cali-
bration of VW spray bars, will become present if
VW is selected for bar control.
Second Screen
This screen allows the setting of the Spray De-
lay On and Off times. The Spray Delay On is the
amountof time, inseconds, after theMaster Spray
switch is turned on that the spray bar valves will
be turned on. The Spray Delay Off is the amount
of time, in seconds, after the Master Spray switch
isturned offthat thespray bar valveswill be turned
off.These delays allow time for the 4-way valve to
turn before open and closing the spray bar. Physi-
cal delays within the mechanical controls of these
valves may have significantly changed and should
be addresed before making significant deviations
from 0.20 seconds.
Third Screen
This screen allows for selection of the hydraulic
motor speed sensor pulses per revolution. The
correct setting is dependent upon displacement.
Holding the VALUE switch will not continuously in-
crement or decrement the value. Two values are
currently valid for the motor: 43 for 1.53 cubic
inches per revolution (CIR) motor, and 46 for both
2.1 and 2.69 CIR motors.
This screen is used to set the flow factor. The
flow factor is the calibration factor for the asphalt
pump.Changing thevaluefrom 1000(100%) does
not change the pump flow but does change the
displayed
pump rate. Values greater than 1000 in-
crease the displayed pump rate while values less
than 1000 decrease the displayed pump rate. The
flow factor increments or decrements by 0.1% and
should only be changed when you are absolutely
sure that such a correction needs to be made.
